Other AbstractThe space radiation environment observations and applications based on GEO satellites were studied in this paper.The GEO space particles radiation detection by GOES series satellites in abroad and FY-2 series satellites in domestic continuously were presented,and so were the developments of the experience models using for space radiation evaluation of GEO energy electrons which were AE8/AP8,AE9/AP9,POLE,FLUMIC and others.The FY-2 series satellites are the principal observational platforms for covering dynamic weather events and the nearearth space environment in China since 90's of the last century.Three generations of high energy particle detectors have been developed and carried on the satellites to provide continuous and simultaneous monitoring of the geosynchronous energetic particle environment.The characteristics of high energy electrons spectrum under various disturbance states,the fast and slow enhanced events of high energy electrons with MeV level obtained by FY-2 series satellites were introduced.The high energy electrons evolution and solar proton events evolution were analyzed united by FY-2 satellite and GOES-13 and GOES-15 satellites.The observation data obtained by FY-2 series satellites can present the dynamic changes of GEO space high energy particles accurately and sensitively. Compared with results of GOES series satellites in the same period,it can not only gain the consistency in the relative calm period but also obtain the obvious short local difference in strong disturbance period.This provides a possibility to analyze the data of GEO particles radiation joint with multi-satellites,develop complete and complex magnetosphere pictures response to the disturbance and study of electronic particles sourcing,redistribution and loss mechanism.On the three-axis stabilized FY-4 satellite which was launched in 2016,the newest particle instruments are carried and can realize particle detections from multi-directions.All the observations can provide abundant and accurate information of particle dynamics.At the present time,there are only GOES series satellites and FY series satellites can provide continuous records of long term GEO space particle radiation environment.The data accumulation and information abundance will promote the model development for forecast service and space science research in China,which can provide better service of space weather forecast and warning.
